Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a cylinder spare regulation clamping device, includes base 1, two sets of stand 2 are installed at the top of base 1, footstock 3 is installed at the top of stand 2, movable base 4 has been installed to the top intermediate position spiro union of base 1, the top left and right sides of movable base 4 all articulates there is lower plate 5, support spring 6 is all installed to the top left and right sides of movable base 4, just support spring 6's top is connected with the lower plate 5 of adjacent one side, two sets of install recovery spring 7 between the lower plate 5, two sets of lower plate 5 is connected through recovery spring 7, mounting bracket 8 is installed to the bottom of footstock 3, peg graft on the mounting bracket 8 and have stop bolt 9, cup joint two sets of rotation axis 10 on the stop bolt 9, the front side the right side of rotation axis 10 and rear side all weld anchor clamps 11, two sets of install anchor clamps spring 12 between the rotation axis 10, two sets of rotation axis 10 pass through anchor clamps spring 12 are connected, cup joint anchor clamps spring 12 are on the outer wall of stop bolt 9, anchor clamps 11 have the left and right sides 13, the bolt 13 has the bolt 13 is fastened to the left and right sides.

The clamp springs 12 are clamp springs for transversely applying force, the cylindrical pipe fitting is clamped from the upper portion, the rotating shafts 10 are provided with mounting grooves matched with the clamp springs 12, and two groups of wear plates engraved with patterns are mounted on the contact surfaces of the rotating shafts 10, so that the clamp springs 12 are located on the inner sides of the two groups of the rotating shafts 10, friction contact of the two groups of the rotating shafts 10 is avoided, follow-up rotation fixation of the cylindrical pipe fitting is affected, hooks are mounted at two ends of the restoring springs 7, hanging rings matched with the hooks are mounted on the lower clamping plates 5, the restoring springs 7 are conveniently detached and replaced, arc-shaped mounting frames are mounted on the right side and the right side of the lower clamping plates 5, support stability of the cylindrical pipe fitting is improved, and processing of the bottom of the pipe fitting is facilitated.
